STRAW-SKITACKER. A

SPE CIFICATION forming part of Letters Patent No. 287,882, dated November 6, 1883,

Application filed August 6,1883. (No model.)

T0 (tZZ whom it may concern:

Be it known that we, JAMES F. SPRINGER and WILLIAM N. SPRINGER, citizens of the .United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Improved Straw- Stacker, of which the following is a specification.

Our invention relates to improvements in that class of straw-stackers which have a strawcarrier adapted to oscillate horizontally about a fixed vertical pivot. The objects of our improvements are, first, to provide an'improved means for supporting the oscillating straw-carrier, and second, to provide an improved means for driving the same. A

The accompanying drawings illustrate our invention.

Figure 1 is an elevation in perspective.

Fig. 2 is an end elevation of the straw-carrier support.

A represents the ordinary straw-carrier of a thrashing-machine.

b is a light frame, pivoted to A on each side, at c, and suspended by a chain, d,=from each side of the end of A. Between the outer ends of frame b is pivoted another frame, e, the rear or free end of which is adjustable vertically in relation to frame I) by means of a screw, j.

Secured rigidly upon. the upper surface of frame 6 is a vertical pivot-pin, g, and a semicircular annular rib, h, concentric with said pm.

13 is a frame having an annular rib, j, corresponding to rib h, and a cross-timber, 7a, through whichtpin 9 passes. Said ribs h and form narrow bearingsurfaces concentric with pin 9. A

The oscillating straw-carrier m is mounted, by means of a pin secured to each side, on uprights Z Z, erected on frame 42. Instead of the usual conveyer-belt, occupying the whole width of the straw-carrier troughs A and m,

v we employ in each case two conveyer-belts,

side by side, having a central space between them,for the purpose of "permitting the use of a central driving-belt. On the driving-shaft n, between the two conveyer-belts, we placea grooved pulley, 0, and on the driving-shaft p we place a similar pulley, 'r. Abelt, 8,

passes from pulley 0 between the vertical idlers 3 3, which are mounted on pivots se I thrasher-support carrier A and the base of carrier m, and a rope, z, passing over a pulley, 1 to a Windlass, 2, supports the free end of carrier m. 1

The operation of our stacker is asfollows: The carriers A and m are placed nearly 1evel,and power is applied to drive shaft 10.. The conveyer-belts on A are carried forward,

and. the conveyer-belts on mare also driven by belt 8. 'As the carrier m is oscillated from side to side to distribute the straw, frame 4; turns on frame 6 about-the pivot g, the belt 8 being prevented from running off idlers t t by the vertical idlers 3 3. As the height of the stack increases the free end of carrier A is raised by Windlass y and ropes w w, at the same time raising carrier m bodily, and as the height of the stack is'still more increased the free end 'of carrier m is raised by Windlass 2 and rope z. Whenthe free end of mis raised,

the belt s is kepttaut bythe springsamoving the idlers t t outward.

We claim as our invention- 1. In astraw-stacker, the combination, sub stantially as specified, of a primary straw-carrier hinged to a thrashing-machine, a secondary strawcarrier adapted to turn about a vertical pivot, and a support for said pivot,

and said secondary straw-carrier suspended from the free end of said primary straw-carrier.

' 2. In a straw-stacker, the frame b, vertical idler-pulleys 3 3, frame 0, pivot-pin 9, frame 7:, annular ribs h and j, straw-carrier m, driving-shafts n and p, belt s, grooved pulleys o and 1'", and idler-pulleys t t, mounted in yielding bearings, all combined and arranged to co-operate substantially as specified.
